I would point you over to the "Fallacy of Grey" if we are beginning to split hairs over the likelihood of Thor existing. You are right that nothing that is non-tautological can ever be proven with absolute certainty, and this category includes the existence of God and a predicted sunrise every day - however, to function rationally we must give claims the appropriate level of credence that supporting evidence demands; we must not turn a critique against binary black-white causality into a unitary embrace of the grey.
Viewed in this light, I don't really think "gnostic" atheism has much use as a term, as it is nonexistent just as "gnostic" anything-non-tautological is nonexistent. Thus quibbling that the neo-atheists are in fact foolish gnostics is really a little petty, when really just about every rationalist falls into the agnostic category as a matter of principle; which still allows us to maintain a category of very very high unbelief in things like God.
